“…Using the back-emf of BLDC motor the cob-web building controller produces the pulses that is given to the switches of inverter and the switch controlling capacitor. From [1] the buck model analysis of BLDC motor shows that the torque produced as output of motor is analysed using two regions. In region 2, the torque ripples seems to be at the highest value.…”

“…There has been many previous works that are present which provides many different analysis and methods to reduce torque ripples. In the work [1], a buck converter analysis can be used to analyse the torque ripples but the absence of the capacitor shows the presence of the torque ripples. In [2], using the model, constant speed operation of a BLDC motor drive operated without a DC link capacitor is analyzed.…”

The BLDC motors have become a very common choice for most of industrial applications because of its reliability and other characteristics of improved efficiency, high torque output, better power factor and simple controller designs. Here the mutual torque which is caused due to coupling of rotor magnetic field and stator currents are responsible for pulsating torque or torque ripples occurring in the motors. To remove the ripples several methods are conventionally used. Here a new biologicallyoriented controller design is proposed in this work. The cob-web building activity of spider is utilized to build an algorithm to reduce torque ripples in BLDC motor. A MATLAB/SIMULINK design of proposed system is being compared to conventional methods to show the effectiveness of this method.

El modelamiento de un proceso o una planta es de vital importancia para el diseño de su sistema de control, ya que permite predecir su dinámica y comportamiento ante diferentes circunstancias, entradas, perturbaciones y ruido. El objetivo principal de este trabajo es identificar qué modelo es mejor entre el matemático y el de caja negra para un motor específico de corriente continua sin escobillas de imanes permanentes. Para ello se presenta el modelo matemático de un motor de corriente continua sin escobillas PW16D del fabricante Golden Motor y se compara con su modelo de caja negra, ambos se obtienen a partir de datos experimentales. Dichos datos, el voltaje promedio aplicado y la velocidad angular, se adquieren mediante una tarjeta de adquisición y se importan al ordenador. Las constantes del modelo matemático se estiman mediante un ajuste de curvas basado en algoritmos de mínimos cuadrados no lineales y patrón de búsqueda mediante herramienta computacional. Para la estimación de constantes del modelo matemático mediante mínimos cuadrados no lineales y patrón de búsqueda se obtuvo una bondad de ajuste de 84,88% y 80,48% respectivamente. La bondad de ajuste obtenida por el modelo de caja negra fue de 87,72%. El modelo matemático presentó ligeramente menor bondad de ajuste, pero permite analizar el comportamiento de variables de interés como el consumo de corriente y el torque aplicado al motor. Debido a esto, se concluye que el modelo matemático obtenido mediante datos experimentales del motor sin escobillas PW16D es mejor que su modelo de caja negra.

In recent years, economic and environmental considerations have led the industry towards energy efficient technologies. As a result, in the context of industrial motor drives, Brushless DC (BLDC) and Permanent Magnet Synchronous (PMS) motors have become popular as energy efficient and reliable alternatives for induction motors. Both BLDC and permanent magnet synchronous motors are electronically commutated based on the position of the rotor by using voltage source inverters that consist of a rectifier, a DC link capacitor and an inverter. In comparison to the other electronic components in the circuit, the DC link capacitor has a limited lifetime, which is severely dependent on the ambient operating temperature. However, with advancements in technology, direct power converters such as matrix converters that do not employ DC link capacitors are becoming popular in industry. At present, matrix converters and similar style direct converters are economically feasible in high power applications and are expected to be economically feasible for low power ratings in the future.
